HLSL uses CreateRuntimeFunction for three intrinsics. This is pretty unusual thing to do, and doesn't match what the rest of the file does. I suspect this might be because these are convergent calls, but the intrinsics themselves are already marked convergent, so it's not necessary for clang to manually add the attribute. This does lose the spir_func CC on the intrinsic declaration, but again, CC should not be relevant to intrinsics at all.
